Yesterday all was ok. Not moving and moving man had good quality.
But today after opening my project the picture quality was bad like there are wholes in the forms
or like a pixel graphic:

And if I animate the quality is even worse:

On the first picture on the right side you can see the layers. I think yesterday there were a little red dot
in every layer. But now there aren't red dots anymore. So I think thats the reason for bad quality.
How can I get the red dots back to get better quality?
And yesterday I had the problem if I moving layers around the red dots where away and I had to redraw.
So what can I do to get good quality again?
Have I to have the red dots in the layers for good quality and why the red dots
are going away so often?
